Vulnerability from pysec - Published: 2026-07-24 15:19 - Updated: 2026-08-19 13:09

Details

Datasets through 5.0.0, fixed in commit f989ef9, contains a path traversal vulnerability in folder-based dataset builders where the file_name metadata field is not properly validated before being joined to the dataset directory. Attackers can supply crafted file_name values with directory traversal sequences to read arbitrary local files, which are then embedded into output when save_to_disk or push_to_hub is called.

Severity

6.9 (Medium)
